Quick Answer: The Line Shaft Unit demonstrates the cycle of energy change from electrical to mechanical to potential energy stored in a raised mass, then back to mechanical and finally electrical energy that lights a lamp.
Last updated: October 2026
Key Features
Shaft extends 50 mm beyond the end of the baseboard
A pair of collars on the shaft forms the winding drum for the cord
Shows energy stored as potential energy in a raised mass
Completes the cycle with electrical energy used to light a lamp
About This Product
The unit follows energy from electrical to mechanical form, then to potential energy stored in a mass raised by the cord on the winding drum. The energy then returns to mechanical form and finally to electrical energy that lights the lamp.
Frequently Asked Questions
Q1. What forms the winding drum? A pair of collars on the shaft, which extends 50 mm beyond the end of the baseboard, forms the winding drum for the cord.
